Voice actor Will Arnett uses his “Batman voice” to discipline his kids, he says.

“I don’t yell at my kids when they’re bad. I just don’t. I don’t believe in it. I will sometimes say, ‘Guys, turn off the iPad,’ and when they don’t, I’m like, [in my Batman voice,] ‘Hey, turn off the iPad.’ And that usually works,” he said at a “Teen Titans Go! to the Movies” event hosted by TheMoms.com’s “Mamarazzi” show.
